I could be really REALLY mean, and kill Aranor at the VERY very end, after they defeat Unia. Evelune kills Unia, and as they stand there triumphant, one Cultists freaks out and shoots an arrow or throws a dagger at Eve, and similar to how she saved him so long ago, Aranor threw himself in front of her, taking the arrow/dagger to the heart.

"As he lay there, the cold steel embedded in his chest, he couldn't help but chuckle weakly. He could feel the blood rising in the back of his throat, but that didn't matter. Eve was safe, he had protected her at the very end. He had ensured she would live to see the fruition of her effort, see her dream made a reality. He wouldn't be walking along that path with her, into the future, but that was alright. A life of peace and quiet? That wasn't meant for him. The military of the rebellion was no longer needed, a gentle, loving hand was needed now, and that hand was not his. Eve's hand was the hand that was needed, his own rough, armoured hand no longer needed to draw a blade to defend her. He had served his purpose, and he had kept his promise. As he felt the coldness engulf him, and he sunk into his own exhaustion, a small smile formed on his lips. And so died Aranor Vaelor, co-commander of the rebellion, a smile on his face."

He who sits upon the throne of winter shall find no enemy able to burn fiercly enough to oppose him

No no, no no no. You do that and you’re banned >:( at least let them both be happy. Eve stabs herself in the stomach to defeat him anyways, remember? She doesn’t die, but his soul is ‘destroyed’ because it’s half of the vessel (her) was damaged.
